In an aspect, a parent node sends a conditional grant for UL transmission to an IAB MT of IAB node. A triggering event for the conditional grant is based at least in part on a communication status of IAB DU of the IAB node (e.g., whether IAB DU is receiving or transmitting data, depending on IAB node duplex capability). In another aspect, IAB DU of IAB node sends a conditional grant for DL transmission to child node. A triggering event for the conditional grant is based at least in part on a communication status of IAB MT of the IAB node (e.g., whether IAB MT is receiving or transmitting data, depending on IAB node duplex capability).
